ToA all whom 'it` may concern:

y Be it known that I, FRnDmE H. REID, acitizenoiv the United States, and a resident of Sioux City,"ihthe`v county of Woodbury and State of Iowa, have'i'nvented an Improved Centrifugal Liquid-Separator, o which the following i's a specification.

M y invention is an improvement. upon thatifor whichv lhave made application for Letters Patent No. 311,924.

'.[h'a've simplified andimproved the construction `and increased the efficiency of the original apparatus in the manner illustrated in the accompanying drawings, in which- 'l .Figure lis a central verticalfsection 'of my improved separator. Fig'. 2 is a` cross lsection on the line 2 2 oi Fig. 1, the same being reduc-ed in diameter. Fig. 3 is a horizontal sectionon the line 3-.3 of Fig. 1. Figfi is a plan viewof a portion ofthe apparatus termed the divider and'which inally divides the cream from the 'skimmed milk. Fig. 5 isin parta side viewand in 'part a lvertical section of-,aportion of the 4apparatus termed the distributing core. l

In Fig. 1 the numeral l indicates -a vertical shaft collar l, a cylindrical body 2? and top part 2f bueing formed witha vertical cylindrical portion and a downwardly inclined'lateral portion, the two beingconnected at the top bf the drum or cylinder-2a Where a gasket 3h is inserted to forma liquid-tight joint.

f nplace of extending the shaft 1 to the top of the/AV Jout into a thin sheet, and must travel a quarter around the circumference oi the plate 8 before it canind exittherefrom.` Thus passage ofthe liquid through the*- se'parator'proper, as in my former inventiomit extends but a short distance above the base 2i oi the bowl of the separator proper, anda tube 4 is scr'ewed thereon, the same extending above the top of the bowl where it is provided with a collar 4 that rests on the inwardly projecting collar 2e formed on the top portion 2b ofthe bowl. Itis obvious that by screwing down the tribe 4 it will hold the parts composing the bowlin close contact's'o as 13o-form liquid-tight joints. INear its lower end the tube 4 is provided with lateral openings 4b' through'which the full milk is discharged into an annular'chamber k5 formed in the upper portion of the slotted piece 6, which, in view of its position and func-Al I tion, may be conveniently designated as the distributing core. From theannular chamber 5 passages 5in lead outward, or laterally, and 'from these the full milk is discharged. The upper portionpf the core 6 is formed, see Figs.l 1 and 5 cji a series oithin blades 6a which project upward alongside,/and in contact with, the tube 4. These blades serve 's/,guides'and supports fora series of skir'sning, orse'parat'ing, plates and a vcovery therefor,

ther'ssme, being indicated by the numerals 7, 8 9, 10,

firom each otherby means of. blocks or bosses, asvisusual in this class of machines. Theu'pper or angular portionsv ofthe several skimming plates are imperforate, i v

but lthe approximately vertical portions are provided witha seriesfof perforations. It is, however, a distinguishing feature of'my invention that the perforations I lof theone plate do not` coincide with those of the next. In otherl words,`the openings 111 are arranged staggered, or lw(l1at may be termed quartering. Thus, there are two openingsgin each of the skimming plates and they 4 are `arranged'diarnetrically opposite, as 'will be seen'in Fig. 5.', and the plates are so adjusted that the openings oi one are removed 90 from. those ofthe next one.

The full milk is delivered into the top of the tube 4 and passes through the openings 4b in its lower portion. into the annular space, or chamber, 5 in the distributing core, whence it is delivered from the lower openings 5.-

into contact with the inner side of the inner skimming plate 7, whereby it is spread out into a thin annular sheet or over the entire surface of the perforated por-tion of suclV plate. The separation of the cream'from the milk begins at this point.. The liquid can find exit onlythrough the openings 14 in the plate i7, that is to say, ontwo opposite sides ofsaid' plate, and in passing. therefrom is delivered into contact with the imperiorate portions of the second plate 8, where itis again spread several plates involves a lateral travel of for each plate in the series. During all the time that the liquid is making this passage the cream-is beingA separated 'from the'v milk. The milk which ,reaches the last orv outer skimming plate contains little or perhaps no cream and` is properly skim milk. This forms a layer against the inner side of thedruni', or cylinder 2a and passes 'upwardalong the side of tlie same andincontact with -16, see Fig. 1.l The cream as is well understood is not p l.100' "the conicalportion of the'"top Zbrnto the chamber 15 therein, whence'it escapes through the lateralfopening los 'milk at the last it isremoved and finally separated from the skimmed milk at the point 17, Fig. 1, where it passes betweenl the `cover plate 12 and divider 13 and is thus-conducted along the under surfacevof the latter and in to the vertical passage 18. v I l It is'to be' understood ,that the machine or apparatus will in' practice be provided 'with receiving pans for cream and milk which are discharged laterally, the

` same being suitably arranged upon the neck or top of the separator. The guide passage i8 is formed of a channel piece, see Fig. 4, which is secured permanently to the divider 13 by a screw 20 and also by soldering. The iinperorate cover plate l2 extends downward from the series of skimming plates proper 7-11, to about the middle of the length of their lower portions so that the milk escaping through the upper openings of the outer skimming plate l1 must pass down below the lower edge oi the cover plate l2 in order to find final exit in contact with the inner side of the drum 2'1. In otherwords, the

cover plate serves to guide the milk downward so that.

it is more completely distributed against the side ofthe drumZ before passing upward to be finally separated `by the divider 13. It will be noted also that the blades 6 projecting upward from the body of the core distributer 6 providespaees or channels'through which the -cream may pass upward until it reaches the dividing plate 13, from which it escapes through the conductor It. will be understood, however, that this largest portion of the cream is that which is separated in the first Contact of the liquid with the skimming plates 7, 8, 9.

short and therefore the cream is 'delivered from the separator bowl more rapidly and has greater density.

I claim- 1. In a separatorl of the class indicated, the combination, with the vertical shaft 1, the bowl 2, 2, seated thereon. a series oi boWLSbape perforated skimming,r plates contained within the bowl proper, the milk tube el having lateral openings and screwed upon the end of said shaft projecting abovi` the base of the bowl, of the distributing core (i, arranged eoncentrically with the milk tube, and having an annular chamber 5, and lateral orifices 5 in register with the discharge openings of the milk tube, the core having also a series of vertical blades 6 projecting from its top portion and spaced apart, their inner edges abuttinf.r the milk tube, and thus forming a series of vertical passages between said tube and the inner skimming plate, as shown and described.

2. In a separator of the class indicated, the combination with the vertical shaft l, the bowl seated thereon, the milk-conducting tube 4 having lateral discharge openings, tbe distributing core 6 surrounding the tube and having lateral openings, and a series of spaced projections 6 extending upward, their inner edges being in Contact with the milk tube, a series of inverted bowl-shape skimming plates held on said projections of the core, and a dividing plate 13 fixed on the tube hi'and extending over tue tops of the said projections and part way down over the outer skimming plate, and havin;r the vertical creamconductor 18, which extends upward from the top of the said dividing plate and connecting,r `with an exit opening in the top of the bowl,. a continuous cream passage being thus formedby and between the vertical projections of the core-and the said conductor 18, as shown and described.
